| 摘 要： | 为解决土地适宜性评价中因子权重选取的主观性和随意性问题,以夏橙产区为例,引入模糊证据权法.评价结果显示:85％的已知适宜点处于修正后验概率分级图的中等适宜级别以上,表明集数据驱动和知识驱动为一体的模糊证据权法与修正后验概率模型结合可以客观、准确地对土地进行适宜性评价.

| Abstract: | To solve the problem of subjectivity and arbitrariness,fuzzy weights of evidence method was introduced to a summer orange production areas for land suitability evaluation.Evaluation results showed that 85% of the known appropriate points were in the revised medium-appropriate level,indicating that the fuzzy weights which integrated data-driven and knowledge-driven,as long as combined with modified posterior probability model,could achieve an objective and accurate measurement for land suitability evaluation... |
